Dr. Theodolou is absolutely amazing. My cancer journey now has me seeing her every other month instead of monthly. I’m happy that I’m at this point with less doctors appointments but I’m sad that I don’t get to see her monthly. Love her!

Of course my diagnosis was unplanned and my path is unknown, Dr Theodoulou was just wonderful she made my husband and I feel like we were in the best hands, I wish we had met Dr Theodoulou under different circumstances but we are blessed that she is in our lives now
